EARL EDXVIN HANSON, OF SPOKANE, ASHINGTON.

Locomotive-ENGINE.

PECIFICATION forming part of Letters Patent No. 522,880, dated July 10, 1894.

Application filed March 23, 1894:.

of which the following is a specification.

My invention relates to an improvementin spark-arresters for locomotives and more par:

ticularly to locomotives in which the draft deposits the sparksin a forward compartment or spark box, and the smoke escapes through the smoke stack after passing through a diagonal screen located in thesmoke arch. And the objects of my invention are to provide an unobstructed passage for the sparks into the spark box; to utilize the entire space occupied by the smoke arch for the escape of the smoke and gases, at need, and to adjust such space from the engine cab simultaneously with the draft without interfering with the operation of the diagonal screen extending And to this end my invention consists in providing a vertical removable plate dividing the smoke arch from the spark box, a diagonal screen extending from the upper edge of a horizontal opening in the top of the division plate entirely across the smoke arch to the lower fixed edge of the diaphragm or baffling plate, the said v diaphragm having a lower extension adjustable vertically and horizontally by means of suitable connections from the engine cab.

In the accompanying drawings which illustrate my invention Figure 1 is a longitudinal Vertical section of the extension of alocomotive engine including part of the boiler showing the construction of my improved sparkarrester. Fig. 2 is a transverse vertical section in front of the division plate on the line 2-2 of Fig. 1. Fig. 3 is a transverse vertical section in front of the diaphragm on the line S of Fig. 1. Fig. 1 is a front View of the adjustable portion of the diaphragm or-baf fling plate and Fig. 5 is a side view partly in section of the same.

A, B, 0, Figs. 1 and 2 represent the sectional division plate between the smoke arch D and the spark box E. It consists of an upper stationary section A permanently attached to the upper part of the extension, and the two lower removable sections B and C seated in the groove G in the wall of the ex- Serial No. 504,876. (No model.)

tension and held together by the straps H I or by other well known devices.

Between the bottom of the permanent section A and the topof the removable sections B O, I provide a horizontal opening F for the admittance of sparks from the smoke arch D to the spark box E. I find a width of about four inches for the opening F to give satisfactory results.

The bottom rim of the stationary plate A is flared up and inward in the direction of the spark box E as shown at a and the top edges of the movable plates B and C are slightly flared in the same direction as shown at c. v y

J is the stationary diaphragm or baffling plate which is attached to the flue sheet K below the dry pipe L and above the first set of fines.

N is the movable diaphragm or battling plate extension for adjusting the open space of the smoke arch D and regulating the draft.

M is a diagonal convex wire netting fastened at its lower edge to the rim j of the stationary diaphragm J and at its upper edge to the rim a of. the stationary division plate A above the aperture F of the spark box E.

O is the exhaust pipe of the engine.

The movable diaphragm plate N is raised and lowered and moved in and out by the mechanism more clearly shown in Figs. 4 and 5 in which Q is a tubular shaft extending horizontally through the smoke arch D at a suitable distance below and away from the rim j of the stationary diaphragm J and mounted in horizontal bearings 'l T in the sides of the locomotive extension through which it passes on one side to the exterior of the smoke arch Where it is connected to the lever S and is rocked from the engine cab by means of the rod S. The lower ed go of the diaphragm plate N is connected to the tubular shaft Q by the pivoted rods q which have alimited longitudinal play in the tubular arms q of the shaft Q, while the upperpart of the plate N rests in the horizontal groove or slot J formed in the lower part of the stationary diaphragm J by the elastic double walls jj or in anyother suitable way.

1? is a shaft rocking within the tubular shaft Q and having the link arms p 11. passing through suitable slots in the tubular shaft Q.

and also pivoted to theiower edge of the plate N. A rocking motion is imparted to the shaft P by means of the lever B secured to it on the outside of the engine and connected by the rod R to the cab. It is thus seen that by rocking the shaft Q an up and down movement is imparted to the diaphragm N and by rocking the shaft P an in and out movement is imparted to it.

The operation of my invention is as follows: The smoke and gases of combustion and sparks escaping from und r the baffling plate are separated by the screen, the smoke and gases passing out through the smoke stack, and the sparks being guided by the screen into the spark box where they are removed from the constant agitation created by the draft.

Among other ad van tages, my improved construction enables me to use a diagonal screen with a battling plate adjustable to increase or diminish the space in the smoke arch while influencing the draft in proportion and without interfering with the screen and irrespective of the use of a divisional plate between the spark receptacle and the smoke arch; it permits the escape of the smoke and gases of combustion through the whole nnincumbered space of the smoke arch and the full length of the diagonal screen from the lower rim of the stationary bafiiing plate to its connection with the division plate, when desired; it presents an unobstructed passage forthe sparks along the screen which acts as a guide into the spark boxyit gives ready access to the spark box, and it allows the various adj ustments of the baffling plate to be made from the engine cab.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
